Enclosing class:

JavaSECMPInitializer

public static class JavaSECMPInitializer.TempEntityLoader
extends URLClassLoader

This class loader is provided at initialization time to allow us to temporarily load domain classes so we can examine them for annotations. After they are loaded we will throw this class loader away. Transformers can then be registered on the real class loader to allow weaving to occur. It selectively loads classes based on the list of classnames it is instantiated with. Classes not on that list are allowed to be loaded by the parent.
